NELLIS AIR FORCE BASE, Nev. — Summer is almost here and to help beat the heat, air conditioning units will be turned on to ensure a comfortable summer experience.

Not too many people are aware that AC system maintenance is paramount to efficient operation.

“Keeping your residence clean and replacing your air filters every three to four weeks goes a long way to ensuring efficient and reliable operation from you’re AC system,” said James Romero, 99th Civil Engineer Squadron heating, ventilation and air conditioning control systems foreman.

Air filters ensure the evaporator stays clean so heat can be absorbed from the air by the refrigerant passing through the evaporator. If this process does not happen efficiently, many latent mechanical issues occur that ultimately lead to the systems failure.

“Another area of interest is optimizing your AC system’s operation is temperature set points. A comfort cooling AC system is technically considered a high temperature refrigeration system. It is not designated or intended to be operated at temperatures below 68 degrees Fahrenheit,” Romero said. “During peak load operating conditions, the system cannot reach such a low temperature and therefore the systems run times are excessive. This is costly, both in terms of operating cost and in mechanical damage caused to the system.”

By maintaining a clean AC system and proper temperature set points, people can expect to not pay excessive amounts of money on their electric bill or on maintenance costs. If preventative maintenance and appropriate operating parameters are not followed, very expensive and lengthy time consuming repairs should be expected.

Temperature set points help ensure that you are getting the most out of your AC unit, while being cost effective.

According to the Nevada Energy Website’s energy tips, during the warm months, the thermostat should be set to 78-80 degrees Fahrenheit when home, and five to 10 degrees warmer at night or when you’re not home.

Getting into this type of routine can help save money on your electric bill every month.

“We can all reduce our carbon footprint by ensuring that our AC systems are properly maintained and by following the recommended set points of 80 degrees Fahrenheit in the summer and 68 degrees Fahrenheit in the winter,” Romero said.
